Failed to respond to incoming message using data source row correlation

Hi,

What content-type is the request message? From the snippet it appears to be json? Is a JSON Responder being used?

Hi Rex,

Based on the error message the responder thinks the request payload was empty. What does the event monitor show? Event Monitoring can be be turned on by right clicking on the Virtual Asset in the Server View, and selecting the "Start Monitoring" action. The details can be seen in the "Parasoft Event Details" perspective. The details will show what message the responder received and its response.

Are there any errors reported to the details when the request message is sent to the virtual asset? If you could share some information from what you see in the Event Details it would help.

Also, if you're really stuck and need someone to assist you in a more hands-on capacity then I would recommend contacting Parasoft Support for help.

Hi,

This is an interesting request, it seems that the json payload is actually inside of a query? It's not even in a query parameter? This is the first line of the request

POST /api/ValBillerDts?{"payments":[{"tid":"1","payment":{"billerCode"...

The correlation being used is applied to the body of the HTTP request, which in this case is empty. Is the JSON payload supposed to be part of the query in the URL?

Hi,

It can be done but it will mean a script is needed to extract the JSON from the URL string. I attached an example responder for a simple case where the JSON payload and request line looks like this,

POST /jsonQuery?{"key":"hello"}

I configured a JSON Responder by going to

Options > Request Handling > Allow incoming request tools to modify the message before applying data source or multiple response correlations

Then in an Extension Tool attached to the "Incoming Transport Header" I used this script to extract the json from the URL. In my case I noticed the first line was reported by the Extension Tool had an equals, =, sign appened to the end of the JSON. I am not sure why since I didn't add it so in your case you may need to use something different to find the end of the JSON in the first line.

import com.parasoft.api.Application
def extract(input, context) {
text = input.getText()
Application.showMessage(text)

multiline = '' + text
list = multiline.readLines()
firstLine = list[0]
Application.showMessage("firstLine=" + firstLine)
json = firstLine.substring(firstLine.indexOf("?")+1, firstLine.lastIndexOf("="))
Application.showMessage("json=" + json)
return json
}

Hope this helps!

Glad it worked!
